Balancing Chemical Equations

A chemical equation is the representation of the chemical reactions. The LHS consists of the reactants and the RHS consists of the products. Balancing chemical equation is the process of equalising the number of each element in the reactants to the products. Enter the equation directly or by clicking the formula of elements, to balance the equation.

Enter a chemical equation to balance[Chemical Equations Examples: H₂ + O₂ = H₂O
Na₂ + Cl₂ = NaCl]

Example of Chemical Formula Balancer

Consider an equation N₂ + H₂ = NH₃

Step 1 :

Compare the elements in LHS and RHS

Element	LHS	RHS
N	2	1
H	2	3

Step 2 :

To balance, add 2 to the RHS,
Equation : N₂ + H₂ = 2NH₃

Element	LHS	RHS
N	2	2
H	2	6

Step 3 :

Add 3 to H in LHS,
Equation : N₂ + 3H₂ = 2NH₃

Element	LHS	RHS
N	2	2
H	6	6

Hence it is balanced.
